ERP Program Manager at Fiserv
The customer is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a standard template worldwide.
The program also includes the “RISE with SAP” migration and modernization program, which may involve migrating the landscapes of selected country installations to the SAP Private Cloud.
On the stakeholder side, the program reporting line extends to the company’s executive board and that of the implementation partner.
Fiserv Germany’s ERP landscape currently includes several non-standard SAP tools and applications that extend the functionality of the ECC environment and can often be integrated into downstream systems. As part of the transition to SAP S/4HANA, it is essential to assess the core functionality, integration points and future viability of these applications in order to determine their alignment with the target architecture.
The focus of the work is on providing expert advice and assessment to define the scope, strategy and roadmap for transitioning Fiserv Germany’s SAP ECC system to SAP S/4HANA.
The recommended best practices from SAP are followed and a structured approach is used to ensure a smooth transition with minimal disruption while maximizing business value.
This assessment forms the basis for a successful SAP S/4HANA transformation and ensures alignment with industry best practices, regulatory compliance and future scalability.
Migration Strategy Definition – assessment of available transition approaches based on business objectives, technical feasibility and SAP Best Practices.
Technical Readiness Assessment – conducting a system analysis to assess compatibility, custom code impact, data volume management, integration points and infrastructure readiness for SAP S/4HANA.
Business Process Impact Analysis – reviewing the latest business process documentation to define the scope and effort required to implement the necessary functions in SAP S/4HANA and to identify opportunities for process optimization.
Roadmap for Non-SAP Systems and Applications – assessment of third-party and legacy applications regarding their integration with SAP S/4HANA and recommendation of consolidation, migration or replacement strategies.
Deployment & Implementation Planning – defining a phased approach for implementation, including project schedules, risk mitigation strategies and key milestones aligned with business priorities.
This transformation takes place in phases: the Discovery phase leads to the Explore phase, which is followed by the Design phase and finally implementation.

About the technology
What FDDI is
FDDI, or Fiber Distributed Data Interface, is a fiber-optic local area networking standard built around a resilient dual-ring design. It was created for dependable backbone communication across campus networks, data centers and industrial sites. FDDI can continue carrying traffic when a ring segment fails, making fault tolerance central to its architecture.
Where it runs
FDDI appears in legacy campus backbones, control environments, telecommunications facilities and systems that still depend on stable fiber connectivity. It can connect network rooms over longer distances than many older copper-based technologies and support traffic between servers, workstations and network segments. In Germany, specialists may encounter it in established industrial, public-sector and research environments during maintenance or replacement projects.
- Campus and building backbone links
- Industrial and control-site networks
- Legacy data-center interconnects
- Telecommunications infrastructure
Ecosystem and tooling
FDDI work involves dual attachment stations, single attachment stations, concentrators, optical transceivers and ring management. Specialists often combine knowledge of multimode and single-mode fiber, optical budgets, patch panels, media converters and network monitoring. Adjacent expertise can include Ethernet, Token Ring, SONET, TCP/IP, VLANs, SNMP and structured cabling documentation.
When expertise matters
Companies usually bring in freelance specialists when an old backbone must remain stable during migration, when intermittent ring faults are difficult to isolate or when documentation no longer reflects the installed cabling. They may also need an independent assessment before replacing FDDI with switched Ethernet. A strong professional can map dependencies, reduce disruption and leave a clear transition plan.
- Trace ring paths and identify weak links
- Diagnose optical, station and concentrator faults
- Review migration risks and dependencies
- Validate replacement network designs
How projects are delivered
A typical engagement starts with topology records, equipment inventories, optical measurements and traffic requirements. The specialist then checks ring resilience, physical connections, configuration boundaries and operational procedures before recommending repairs or migration steps. Remote analysis works well for documentation and planning, while on-site access may be necessary for fiber inspection, patching and equipment tests in Germany.
Signs of strong professionals
Strong FDDI professionals understand the standard beyond its terminology. They can explain how token passing, dual-ring recovery and concentrator behavior affect availability, then connect those details to business-critical systems. Look for clear test methods, careful change control, precise diagrams and honest advice about whether to preserve, isolate or retire the installation.
Frequently asked questions
Key details about FDDI, drawn from the questions we get asked most.
FDDI is mainly used for resilient fiber-optic backbone networking between buildings, network rooms, servers and industrial systems. Its dual-ring design can maintain communication after certain cable or interface failures, which made it valuable where continuity mattered.
Fiber Distributed Data Interface offers a fault-tolerant ring architecture and predictable token-based access, while modern Ethernet usually provides broader hardware availability, simpler switching and easier integration with current networks. The right choice depends on the existing infrastructure, required continuity and migration risk.
A strong FDDI specialist should understand fiber testing, optical transceivers, concentrators, structured cabling and network monitoring. Experience with Ethernet migration, TCP/IP, VLANs, SNMP and legacy documentation is also useful when the work involves modernization.
The required depth depends on the scope. A documentation review may need familiarity with FDDI terminology and fiber infrastructure, while fault isolation or a live migration calls for a specialist who has handled ring recovery, optical measurements and change control in comparable environments.
FDDI planning, topology reviews and configuration analysis can often be completed remotely. Physical inspections, fiber testing, patch changes and equipment replacement normally require site access, so companies in Germany should define which activities need an on-site presence and which can use remote collaboration.
Ask for a project approach covering topology discovery, optical checks, fault isolation, documentation and rollback planning. A capable FDDI freelancer should explain assumptions clearly and distinguish evidence from guesses before recommending repairs or replacement.
FDDI is rarely the first choice for a new general-purpose network because switched Ethernet and current fiber standards offer a broader modern ecosystem. It can still matter when a legacy installation supports critical operations, when migration must be staged or when its resilience model needs to be assessed.
Quality is visible in accurate ring diagrams, traceable test results, clear fault evidence and practical recommendations. An experienced Fiber Distributed Data Interface professional should also document station types, concentrator paths, optical conditions and the operational impact of every proposed change.
